Vehicle emissions of short-lived and long-lived climate forcers: trends and tradeoffs.

Near-term climate mitigation by short-lived forcers.

Emissions reductions focused on anthropogenic climate-forcing agents with relatively short atmospheric lifetimes, such as methane (CH4) and black carbon, have been suggested as a strategy to reduce the rate of climate change over the next several decades. We find that reductions of methane and black carbon would likely have only a modest impact on near-term global climate warming. Even with max...

Managing short-lived climate forcers in curbing climate change: an atmospheric chemistry synopsis

The Montreal Protocol has set an extraordinary example by applying scientific discoveries, technological innovations, and swift political actions to solving one of the most urgent environmental problems facing humans. With its ongoing implementation, the stratospheric ozone is expected to return to its 1980 levels around mid-twenty-first century. In addition, the Montreal Protocol has contribut...

Supplement of Regional temperature change potentials for short-lived climate forcers based on radiative forcing from multiple models

Disentangling the effects of CO2 and short-lived climate forcer mitigation.

Anthropogenic global warming is driven by emissions of a wide variety of radiative forcers ranging from very short-lived climate forcers (SLCFs), like black carbon, to very long-lived, like CO2. These species are often released from common sources and are therefore intricately linked. However, for reasons of simplification, this CO2-SLCF linkage was often disregarded in long-term projections of...

Multimodel projections of climate change from short-lived emissions due to human activities

[1] We use the GISS (Goddard Institute for Space Studies), GFDL (Geophysical Fluid Dynamics Laboratory) and NCAR (National Center for Atmospheric Research) climate models to study the climate impact of the future evolution of short-lived radiatively active species (ozone and aerosols). The models used mid-range A1B emission scenarios, independently calculated the resulting composition change, a...
